Mac OS X 10.2 can use Mac OS 9 USB Input Sprockets in the Classic environment. Some functions of USB input devices that Mac OS X recognizes are available to Classic environment applications. A Classic game that implements Input Sprockets, for example, may use a USB joystick.
Advanced features of the USB input device may not be available in the Classic environment.
Use a Mac OS X-native (Carbon or Cocoa) version of the software if available, or contact the manufacturer of the USB device for additional compatibility information.
